What is the name of the process used to refine oil into many different products?

The process used to refine crude oil into various products is called fractional distillation. In this process, crude oil is heated in a distillation column, causing it to vaporize. The vapors then rise through the column and cool at different heights, allowing for the separation of various hydrocarbons based on their boiling points. This results in the production of fuels, lubricants, and other petrochemical products.
